Title: Closing device, automatic or otherwise, for ducts carrying liquids or gases, particularly for the ducts of explosion engines
IPC: F02M37/00
Filed: 1931-04-02
Abstract: 376,269. Liquid seals. ERIANN (HOLDING DE BREVETS DE MECANIQUES ET D'ELECTRICITE), 9, Place de la Convention, Issondun, Indre, France. April 2, 1931, No. 10084. Convention date, April 2, 1930. [Class 135.] A liquid seal device for controlling the fuel supply to the carburetter of an internal-combustion engine and adapted to close automatically as soon as the engine prepares to stop, is interposed in the pipe line between the fuel tank and the carburetter. A pipe B connected to the fuel tank dips into mercury M in the bottom of a tank A and a connected bellows N. The space L below the bellows is connected by a pipe G to the induction pipe so that when the engine is running the bellows is expanded against the action of a spring o thus removing the mercury from the mouth of the tube B and allowing fuel to flow out through the pipe E. The bellows may be moved by a push rod U extending through a tube T. The device may be actuated by the pressure in the exhaust pipe or by the expansion of a gas or liquid exposed to the heat of the engine. In a modification the hand actuation is dispensed with and the actuating pressure acts directly on the surface of the mercury.

Title: Improvements in or relating to blades for use in axial-flow rotary bladed machines such as gas turbines
IPC: B23P15/02
Filed: 1956-04-03
Abstract: 801,468. Copy-milling turbine blades. ESCHER WYSS A.G. April 3, 1956 [March 31, 1955], No. 10222/56. Class 83 (3). [Also in Group XXVI] A blade for use in an axial-flow turbine or compressor comprises a profile portion 1 and a thickened root portion 2, the profile form of the profile portion and of the root portion being the same, at least on one side of the blade. The blade may be formed by using profile cutters which are moved outwardly as they approach the root portion. The surfaces of the blade at both sides may be produced simultaneously and the blade may be rotated during machining of the profile portion so as to produce the desired blade twist. The blade may be formed by a series of cutting operations, each forming only a part of the profile; for example the leading and trailing edge portions may be cut simultaneously and finally the centre portion of the profile. A tracer roller corresponding to portions of the profile already cut may be used during machining of subsequent portions of the profile, and to prevent damage by swarf penetrating between the roller and the finished portion of the profile, a rubber covering may be disposed between the cutter and the roller. If only one blade surface is machined at a time, the blade twist may be provided either by movement of the cutter or by turning the blade support. A complementary member 14 is disposed on at least one side of the blade root 13. The engaging faces of the root 13 and member 14 may be of corrugated form as shown in Fig. 7, the corrugated face of the root being produced by undulatory transverse movement of the profile cutter. The flat-faced blank from which the concave surface 10, Fig. 6, is cut may have a width terminating at 11 so that as the cutter 10<SP>1</SP> is withdrawn to produce the thickened root, it leaves the flat surface 11 to engage a flat complementary member 14.

Title: Improvements in the catalytic manufacture and production of gases containing hydrogen and in the preparation of catalysts therefor
IPC: C01B3/40
Filed: 1931-04-10
Abstract: Hydrogen is obtained by treating hydrocarbons having a higher molecular weight than methane with a gas capable of converting carbon into carbon monoxide such as steam, oxygen or carbon dioxide at a temperature between 400-1000 DEG  C., preferably between 600-800 DEG C. and more particularly between 700-750 DEG  C., in the presence of a catalyst obtained by making an aqueous paste comprising at least one substance from the metals of the iron group, their oxides, hydroxides or carbonates and a hydraulic binding agent, and allowing the paste to set.  The catalyst may contain from 20-90 per cent of binding agent.  Suitable binding agents contain 10 per cent or more of alkaline earth metal oxides or magnesium oxide, preferably commercial cements.  Alumina cement, Portland cement, iron Portland cement, blast furnace cements and hydraulic cements of natural origin are also suitable. Aluminates having hydraulic bonding properties may also be used, such as alkaline earth or heavy metal aluminates, e.g. calcium aluminates, aluminates of magnesium, iron and nickel and aluminates containing several elements as the basic components of the molecule.  The catalysts may be activated, for example by the addition of difficulty reducible oxides of metals of the 2nd to the 6th group of the periodic system, e.g. oxides of aluminium, magnesium, calcium, uranium, chromium, molybdenum, vanadium, thorium, cerium, &c.  The amount of activating agents added is variable, e.g. from 0,1 to 10 molecular proportions for each molecular proportion of nickel.  Alumina, magnesia and bauxite may be used as carriers and activating agents.  The gases may be passed successively through several layers of catalysts of gradually increasing activity.  If the oxides or hydroxides of the metals of the iron group are obtained by precipitation, ammonia is preferably used as the precipitating agent as alkalis favour the deposition of carbon.  Elevated, or preferably, atmospheric pressures may be used.  Suitable initial materials include waste gases from the destructive hydrogenation of coals, tars and mineral oils, gases obtained from the dry distillation of solid carbonaceous materials such as coal gas or low-temperature carbonization gases or fractions of these gases, etc. Specification 339,645, [Class 1 (i), Chemical processes &c.], is referred to.

Filed: 1950-05-01
Abstract: 667,911. Aircraft control surfaces. BLACKBURN & GENERAL AIRCRAFT, Ltd. May 1, 1950, No.10721/50. Class 4. A high speed aircraft with variable sweepback wings has movable wing tips 8 and ailerons 9 for lateral control, the former being operable only when the wings are in their high-speed swept-back position and the latter only when the wings are in the low-speed out-spread position. Each wing tip 8 is rotatable about a shaft 10 and is actuated by links 11, 12 and a bell crank 13, while each aileron 9 is operated by links 14, 15 and a bell crank 16. The ends of the free arms of the bell cranks are connected bv a slotted link 17, one end of which is connected by a link 18 to a pilot-operated member 20. When the control surfaces are operated the link 17 pivots about its point of connection with a link 21, connected by a further link 22 and bell crank 23 to one end of a rod 24 whose other end is pivotally attached to the fuselage at a point 25 which is offset relatively to the wing pivot 4. In the lowspeed position, Figs. 1 and 4, the fulcrum of link 17 is disposed above the end of the free arm of bell crank 13, whereby movement of the control member 20 results in rotation of bell crank 16, to actuate the aileron 9. Displacement of the wing into the swept-back position causes movement of members 23, 22, 21 whereby the fulcrum of link 17 is moved into a position above the end of the free arm of bell crank 16 (Fig. 5), so that control member 20 actuates the bell crank 13 and the wing tip 8. If either surface is in operation when the wing is moved, control is transferred progressively to the other surface,
Patent GB-454723-A (GB)
Title: Improvements in or relating to the preparation of acylated polyalkylene polyamines
IPC: B23F7/00
Filed: 1935-04-06
Abstract: Polyalkylene polyamines are caused to react with amides of aliphatic or cycloaliphatic carboxylic acids containing at least 8 carbon atoms, whereby acylation of the polyamines takes place and a volatile base is split off.  The removal of the latter may be assisted by passing dry CO2-free air through the mixture. According to the examples, the reaction mixture is heated to about 180 DEG  C., until a test portion is soluble in dilute hydrochloric acid, and the pressure may be lowered towards the end of the reaction.  Specified polyalkylene polyamines are the reaction products of ammonia with ethylene, propylene, butylene, and like dichlorides.  These are usually mixtures of several components, e.g. dialkylene triamines, dialkylene tetramines, &c., and may be used either as such or after separation.  Suitable amides are those of oleic, stearic, ricinoleic, or naphthenic acid, which may be substituted in the amino group, e.g. by methyl.  Specification 337,368, [Class 2 (iii)], is referred to.
